Overview

What is the P-Shot®?

The Priapus Shot® is a regenerative injection that uses growth factors isolated from your own blood to stimulate tissue repair, improve blood flow, and enhance nerve function in penile tissue.

Unlike medications that work temporarily by increasing blood flow on demand, the P-Shot® aims to improve the underlying structure and function of the penis over time — making it a fundamentally different class of treatment.

It is commonly used for erectile dysfunction, reduced sensitivity, Peyronie’s disease, and sexual health decline associated with aging, diabetes, or post-prostate treatment recovery.

What is PRP?

Platelet-Rich Plasma (PRP) is created by drawing a small blood sample and spinning it in a centrifuge to concentrate the platelets — cells packed with growth factors that signal tissue repair, new blood vessel formation, and cell regeneration. Because it comes from your own body, there is no risk of allergic reaction and no foreign substances are introduced. PRP has been used in orthopedics, wound care, and dermatology for decades.

Benefits

What the P-Shot® may improve

Results vary by individual. The following reflect outcomes commonly reported by patients and noted in clinical literature — not guarantees.

Function

Stronger, firmer erections

Improved blood flow to penile tissue

Better response to ED medications

Reduced severity of erectile dysfunction

Sensation

Increased sensitivity

Enhanced sexual pleasure

Improved orgasm quality

Restored sensation after nerve damage

Structural

May help reduce Peyronie’s curvature

Supports tissue regeneration and healing

Can contribute to increased fullness when combined with protocols

Treatment advantages

Non-surgical, in-office procedure

No foreign substances — uses your own blood

No downtime — resume normal activity same day

No risk of allergic reaction

What to expect

The procedure, step by step

01

Blood draw

A small sample of blood is drawn from your arm — similar in size to a standard lab test.

02

Centrifuge processing

The blood is spun to separate and concentrate the platelet-rich plasma from other components. This takes approximately 10 minutes.

03

Numbing

A topical numbing cream is applied and left for 20–30 minutes to ensure comfort during injection. Most patients report the numbing makes the procedure well-tolerated.

04

PRP injection

The concentrated PRP is injected into targeted areas of the penis using a fine needle. The injection itself takes only a few minutes.

05

Recovery

No downtime is required. Most men return to normal daily activity immediately. Results develop gradually over 2–6 weeks as tissue responds to the growth factors.

Clinical evidence

PRP therapy for erectile dysfunction has been evaluated in multiple clinical studies. Published research shows promising results for men with mild to moderate ED, particularly those with vascular or nerve-related causes. Large-scale randomized controlled trials are still ongoing. The P-Shot® protocol was developed by Dr. Charles Runels and uses PRP in a specific injection pattern designed for penile tissue. This page reflects current published evidence as of 2026.

FDA status

PRP is FDA-cleared for processing, but the P-Shot® as a specific treatment protocol is not FDA-approved for erectile dysfunction. It is performed as an off-label use of PRP by licensed providers. This is common in regenerative medicine — many established treatments operate under off-label use.

How it compares

P-Shot® vs. related treatments

The P-Shot® is one of several PRP-based and regenerative options available. Here’s how it compares to closely related treatments on this site.

Treatment Type Primary goal Downtime

P-Long Protocol™ PRP + traction protocol Gradual penile lengthening over time None
P-Max™ PRP-based combination Enhanced function and size optimization None
P-Thick™ PRP-based filler Immediate girth enhancement Minimal
Shockwave Therapy Energy-based Vascular repair, ED improvement None

Is it right for you?

Who is a good candidate

The P-Shot® may be appropriate for men who:

Have mild to moderate erectile dysfunction and want a non-pharmaceutical option

Experience reduced sensitivity or changes in sensation with age

Have Peyronie’s disease and want to explore non-surgical treatment

Want to enhance the effects of existing ED medications

Are recovering from prostate treatment and want to support tissue healing

Have diabetes-related sexual health decline and want a regenerative approach

Are looking to optimize or combine with other enhancement protocols

Common questions

Frequently asked questions

Does the P-Shot® hurt? +

Most patients report minimal discomfort. Topical numbing cream is applied beforehand and left on for 20–30 minutes, which makes the injection well-tolerated for the majority of men. Some report a mild pressure sensation during injection but not significant pain.

How long do results last? +

Results typically last 12–18 months, though this varies based on individual health, lifestyle, and whether additional treatments are used. Maintenance sessions are generally recommended annually to sustain results.

How many treatments will I need? +

Most providers recommend starting with one treatment and reassessing at 6–8 weeks. Some men see significant improvement after a single session; others benefit from a second treatment. Your provider will guide the plan based on your response.

Is the P-Shot® FDA approved? +

PRP itself is FDA-cleared for processing. The P-Shot® as a specific treatment protocol is not FDA-approved for erectile dysfunction — it is performed as an off-label use of PRP. Off-label use is legal and common in medicine, particularly in regenerative therapies.

How is it different from Viagra or Cialis? +

ED medications work temporarily by increasing blood flow on demand. The P-Shot® works differently — it aims to improve the underlying tissue quality and vascular health of the penis over time. Some men use both: the P-Shot® to address root causes, and medication as needed in the interim.

Can the P-Shot® increase size? +

The P-Shot® alone is not primarily a size enhancement treatment. It can improve fullness and tissue quality. For more noticeable size improvement, it is often used in combination with protocols like P-Long™ or P-Max™. Discuss realistic expectations with your provider.

When will I see results? +

Some changes may be noticeable within the first 2–3 weeks. Most men see continued improvement over 2–6 months as tissue responds to the growth factors. Results are gradual — this is not an immediate fix like a medication.
